SELF-ADJUSTING HEADLIGHT FOR AUTOMOBILES.

Specification of Letters Patent.

Patented Oct. 9, 1917.

*Application led April 9, 1.917. Serial No. 160,667.

To all witom t 'may concern.'

Be it known that I, HARVEY H.'Hor, a

citizen of the United States, and resident' of St. Louis, Missouri, have invented certain new and useful Improvementsin Self- Adjusting Headlights 4:for Automobiles, of which the lfollowing is a specilicationzcon` taining a full, clear, and exact description,

' reference being had' to the accompanying drawings, forming a part hereof.

l My invention re ates to an improved lamp supporting and operating means for automobiles,` and it consists in the novel construction and arrangement of parts hereinafter described and particularly ointed out in the claim found at the end ofp this speciication. n

The object of my invention is to provide an improved mechanism for automatically turning the lamps or headlights of automobiles whenever the steering-wheel is turned; for the purpose of enabling the driver to clearlysee t e road at all times when driving at night, and particularly when approaching (or driving upon) a curve in the road.

In the drawing,

Figure 1`I is a plan view of the front portionl of an automobile having my invention applied thereto.

Fig. 2 is a front-end elevation of an automobile having my invention applied thereto, and

Fig.l 3 is a detail sectional side-elevation of a lamp or headlight and its immediate connections.

' or frame; `7 the spring which'supports the front end of the chassis; and 8 the usual rod which extends to the steering-post.

The numeral- 9 designates the lamps or headlights-,'"which are provided upon their` undersi/des with vertic journals 10 mounted/to rotate or rock in bearings 11 of brackets [2 fixed to the chassis or frame 6, the said vtendin braeketshaving integral fender-arms 1 3 exoutwardly, and upon which the 'front enders 14 are supported.

Beneath the bearings 11 lcommon lock-l nuts 15 are mounted upon the said ournals lof the lamps, to prevent vertical movement of said journals in said' bearings 11.

'The said lamp-journals 10 are extended downwardly a distance, and have fixed upon their lower ends L-shaped sockets 16, thel horizontal arm ofpwhich has fixed in it a rearwardly-extending crank-arm `-17, the rear end of 'the latter being pivotally connected to a horizontal connecting-rod 18.

Said connecting-rod 18 extends parallel with the said steering gear rod 3, and pivotally connects the crank-arms 17 of the two lamps 9, so that whenever one of said lamps is rotated the other lamp will be rotated a like distance in the same direction.

A clamp 19 is fixed upon said connecting rod 18 at about the center of the length of the latter, by means of suitable bolts 20, and said clamp is formed withl a socket 21 which projects rearwardly from said clamp.

Fixed within said socket 21 is the horizontal arm of an L-shaped lampturning bar 22, the vertical arm of which is mounted to slide in a bearing 23 formed integral with another clamp 24 that is fixed by means of bolts 25 upon the said steering-gear rod 3, at the center of the length of the latter, so that whenever the steering-gear rod is moved by its steering-post rod 8 the said lamp-turning bar and the lamp-connecting rod 18, as well as the lamps 9, will be turned at the same time.

A common split-pin or cotter 26 is passed through a perforation in the said vertical arm of saidlamp-turning bar 22, at a point below the said bearing 23, to prevent said arm from passing out of said bearing accidentally when subjected to any undue strain during the operation of the automobile upon rough roads.

From the above description of my invention the operation of the same will be clear to those skilled in the art, and further explanation is deemed unnecessary, except to say that the vertical arm of the said lampturnin bar v22 moves freely up and down in its gearing` 23 as the chassis of the automobile moves upon the springs which sup.

port it; so that there is a ositive connection, at all times, lbetween t e steering gear rod 3 andthe lamps 9, thereby insuring their being turned in the proper direction io throw tho iight the amps upon tho road at a mes, no if the rooc he 'straight or Gamed.

What I cla-im ma lowing:

An improved Las-oh headghts of an mlom tnz'nod Wheneve; `1; is wme. io :zer the 7 mobile; oonosing a vertical omfna o waa-tion is the fol- ?ol causing the to be. posltlvely: ing-gear thereof manon of the autoaoob.' having' a o JJ n 'nga 'brad-mts being fixe-5i to some part of he zmxe upon said horizontal rod; an L-shaped bmp-turning bar having its horizontal .arm fixed in said socket; the steering-rod of an automobile; and a bearing fixed upon said steerngrodso that the vertical arm of said lamp-turning bar may slide within Esaid bearing last mentioned as the chassis of the automobile moves up :m down upon its spring.

.in testimony whei'eof, I have signed my name to this specific-ation, in presence of two subscribing Witnesses.

HARVEY H. HOY.
